Want a Critique on my pictures....
In my opinion:
In 1 the tree on the left overpowers the picture try cropping back to get rid of most of it
the cat is out of focus because the speed is to low. Increase the ISO until your speed is about 2x the focal length
the tree is in focus but the messy out of focus background spoils it - what were your objectives with this picture
These might help:
good luck keep shooting
